CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 684,517, dated October15, 1901.

Application filed m 18, 1901.

T0 aZZ whom, it may concern:

Be it known that I, WILLIAM MARKY, a citizen of the United States,residing at Sloan, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Gar-Doors, of which thefollowing is a specification.

This invention relates to an improved cardoor, such as are used on carsloaded with grain, coal, or any other small loose freight usuallyshipped in box-cars.

The object of this invention is the production of a door which isoperative in sections, simple in construction, capable of withstandingsevere strains, and which is readily manipulated.

Another object is the production of a door which when the propersections are opened offer superior facilities in loading the car withlumber.

A still further object is to so connect the sections together that nograin can pass out between the same when the car vibrates and thesections move toward and from each other.

I attain these objects by the novel construction, arrangement, andcombination of parts set forth in the claims and illustrated in theaccompanying drawings, in which- Figure l is a side elevation of abox-car, showing the outerdoor open and my improved inner door appliedthereto. Fig. 2 is a lougitudinal section through the car, showing themanner in which my inner door is applied to the inside of the car. Fig.3 is a vertical section taken on line 3 3, Fig. 1, showing thevertically-swinging section of the door in its elevated or openposition. Fig. 4 is a similar view showing the lower sliding section andthe horizontally-swinging section in an open position. Fig. 5 is adetached side view of the lower sliding section of the door, the platewhich covers the gear-rack being removed. Fig. 6 is a fragmentaryelevation of a portion of the car, showing the manner in which thesliding section of the door is locked. Fig. '7 is a vertical sectiontaken on line 7 7, Fig. 1, illustrating the fastening device for thehorizontally-swinging section. Fig. 8 is a vertical section taken online 8 8, Fig. 1, showing the manner of locking the sliding section ofthe door. Fig. 9 is a detached fragmentary Serial No. 60,807. (Nomodel.)

Referring now to the drawings, like letters of reference refer to likeparts in the several figures.

The letter A designates the car-body, B the outer door, which issuspended on a track 0 in the ordinary manner and which is capable ofbeing moved horizontally thereon.

D is the doorway or opening.

The inner door is formed of an upper vertically-swinging section E,which is hinged to the header of the door-opening by means of hinges e,and it is somewhat longer than the width of the door-opening, so that itbears against the inner faces of the doorjambs e when in its closedposition. A horizontally-swinging section F is located below the sectionE, and it is secured by means of hinges fto the jamb e on one side ofthe door-opening. Secured to the lower central portion of thevertically-swinging section E is a hasp G, which passes over a staple F,formed on the said horizontally-swingingsection, a Wedge-key beingpreferably used to lock them both together. Any suitable arrangement forlocking the free end of the sec tion F to the other door-jamb may beprovided; but the preferred embodiment Ihave shown by the locking-catchg, which is pivotally secured to the section and made to enter avertical groove 9, arranged in the face ofthe door-jamb, in whichposition it is held by a keeper 9*, pivoted to said jamb and arranged tobear against the upper edge of the catch g.

H designates a guide-bar hinged at one end to the door-jamb directlybelow the section F by means of a hinge h, and it is fastened at itsopposite end by a staple secured to the door-jamb and passing through anopening or slot 1-1, formed in the free end of the guidebar, a wedge-keybeing provided to enter the eye of the staple, said guide-bar beingarranged to swing horizontally, but under ordi nary circumstances toremain closed. Ar

bar H. The latter has an upwardly-projectin g flange 72., which overlapsthe lower end of the section F, and it is also provided with a guideway7L2 in its under side in which, with the guide H and the guide 72,secured to the floor of the car, the lower sliding section I is guided.By this construction of the guideway the sections may move on or withineach other when the car vibrates without allowing the loss of any grainwhatever. The section I is slidable longitudinally of the car and has arack-bar J formed or secured thereon. An operating-shaft K passesthrough the wall of the car near the door-opening and through alongitudinal slot or way formed in the sliding section and is providedat its inner end with a gear-wheel K, which meshes with the saidrack-bar and which on turning opens or closes the sliding section,depending on the direction in which the operating shaft is turned. Tothe outer free end of the operating-shaft a handle L is secured, thepreferred connection of the handle to the shaft being by passing thehandle through an opening Z in the shaft and securing the two togetherby means of a split key Z. During transportation or when not in use thehandle may be turned parallel with the side of the car, and thus preventprotruding parts. To look the sliding section of the door and to closethe longitudinal slot or way formed therein, I provide a locking-bar M,which is pivoted at one end to the inside of the car, as shown at m. Ashort distance from its pivoted end the locking-bar is provided with anoffset m, which is adapted to swing in rear of an outwardly-projectinglug or car m formed on one end of the sliding section, so as to lock thesame. This locking-bar is held in this position by a pivotal catch N,which engages its free end and which is held in its position against thelocking-bar by a keeper m bearing against the upper edge of the same. Infilling the car with grain, coal, or any other like freight allsections, except the upper vertically-swinging one, are closed, theopening of the upper section affording sufficient space to allow thegrain or coal chute, as the case may be, to be placed therein. Inunloading a car the lower sliding section is opened first. This allowssufficient grain or freight to escape to permit of convenient handlingof the same. In some instances, such as when using cars for bulkyfreight, it is desirable to open all the sections of the door and alsothe guide-bar in which the upper edge of the lower or sliding sectiontravels when closing or opening the same,

while in loading a car with lumber all sections should be opened and theguide-bar closed. In this instance the guide-bar acts as a convenientrest or support on which to swing and shift the lumber.

Having thus described my invention, what I claim is 1.. A car-doorcomprising an upper vertically-swinging section, a lowerlaterally-sliding section, and an intermediate horizontallyswingingsection, substantially as set forth.

2. A car-door comprising an upper vertically-swinging section, ahorizontally-swing ing section directly below the same, a guidebarhaving a flange which overlaps said horizontally-swinging section, and alaterallysliding section below said guide-bar in which it is guided,substantially as set forth.

3. The combination with the door-opening, of a guide-bar having anupwardly-projecting flange on its upper face and a guideway on its underside, a sliding-door section held to slide in said guideway, and aswingingdoor section which the said upwardly-projecting flange isadapted to overlap, substantially as setforth.

4c. The combination with the car, of a sliding car-door having agear-rack arranged lengthwise thereon and having an outwardlyprojectinglug at its one end, an operatingshaft having a handle and passingthrough thecar, a gear-wheel secured to said shaft and meshing with thesaid gear-rack, a locking-bar pivoted to the car and having an off setadapted to engage the said outwardlyprojecting lug, and means forlocking the free end of said bar, substantially as set forth.

5. The combination with the door-opening, of an upwardly-openingdoor-section hinged to the header of said opening, ahorizontallyswinging door-section hinged to one jamb of said opening,means for securing said firstmentioned section to the second-mentionedsection when both are closed, means for locking thehorizontally-swinging section to the other jamb of the opening, aguide-bar which overlaps the lower edge of the saidhorizontally-swinging section and which has a guideway formed on itsunder side, a laterally-sliding section below said guide-bar which isguided in said guideway, and means for lock ing said sliding sectionwhen closed, substantially as set forth.

WILLIAM MARKY.
